Sudhir Power Service Engineer Interview Questions, Process, and Tips

Plant load factor is a measure of the actual output of a power plant compared to its maximum possible output.

• Plant load factor is calculated by dividing the actual energy generated by the plant over a specific period by the maximum possible energy that could have been generated during the same period.

• It is expressed as a percentage and indicates how efficiently a power plant is being utilized.

• A high plant load factor i...read more

Machine availability is the percentage of time a machine is able to be used for its intended purpose.

• Machine availability is calculated by dividing the total operating time by the total time in a given period, then multiplying by 100.

• For example, if a machine operates for 800 hours in a month and there are 1000 total possible operating hours, the availability would be 80%.

• Factors like downtime, maintenance, and repairs

A line diagram of a wind turbine generator (WTG) shows the flow of energy from wind to electricity.

• The diagram typically includes the rotor blades, gearbox, generator, and power electronics

• The blades capture wind energy and turn the rotor, which drives the gearbox

• The gearbox increases the rotational speed and sends it to the generator

• The generator converts the rotational energy into electrical energy

• The power electroni...read more

DFIG converters are used in wind turbines to convert variable frequency AC power to DC power and back to AC power.

• DFIG stands for Doubly Fed Induction Generator

• The converter consists of two back-to-back voltage source converters

• One converter controls the rotor current and the other controls the grid current

• The rotor current is controlled to maintain a constant torque on the turbine

• The grid current is controlled to main...read more

DFIG stands for Doubly Fed Induction Generator, a type of generator used in wind turbines.

• DFIG is a type of generator commonly used in wind turbines

• It has two sets of windings - one connected to the grid and the other connected to a converter

• The converter allows control of the generator's output power and speed

• DFIG is known for its ability to provide variable speed operation and improved efficiency

• It is a popular choic...read more

Wind power is generated by harnessing the kinetic energy of wind to turn turbines, which then convert the energy into electricity.

• Wind turbines capture the kinetic energy of the wind and convert it into mechanical energy.

• The mechanical energy is then used to turn a generator, which produces electricity.

• Wind power is a renewable energy source that is clean and sustainable.

• Wind farms are large areas with multiple wind tu...read more
